robots.txt question

[Kyle]

I'm sure I could figure this out on my own, I just wanted to be 5000% sure I do this right.

How would my robots.txt file look if I wanted to block .php extensions from being crawled by all search engines? Only .php, everything else is allowed.

Thanks!!

I dont think robots.txt files where designed to be that sophisticated.

I take it there's to many different php files to list them individually in robots.txt?

You could put all your .php files in a separate directory and then disallow that directory in robots.txt.

Is there no way to just block *.php?

Just found this (scroll to bottom):

It indicates Google will recognize disallowing of certain file extensions, but other bots may not.

Thank you.. that's extremely helpful!

You could put the robots meta tag on each php page.
